observation balloon
2.A Far Infrared Balloon-borne Photometer for Solar Observation
3.The plastic nuclear track detector CR-39 is exposed for about 10 hours in balloon observation in 1982.The relative abundance (E>3.6 GeV/n) of the galactic cosmic rays is obtained and compared the result with the satellite data.
4.MethodsAfter extradural balloon was filled with normal saline (3-4 ml),alterations of intracranial pressure(ICP),mean artery pressure(MAP),brain-stem auditory evoked potential(BAEP),cerebral and cardiac electricity and respiration were recorded with observation of pupil changes, corneal reflexes,blood flow in ocular fungus and gross changes of brain.
